Consider supporting Collection types as injection target

[cstamas]

Currently injected collection types supported are Set and List, but not Collection.

So something like this is currently not possible:

@Inject
public MyCtor(Collection<MyComponent> myComponents) {
...

Despite I may have Set or List injected. We may want to broaden and recognize these situations as Java would allow passing of Set or List into this ctor.

PS: This just came to my attention, as for example former Aether (Maven Resolver) is full of these:
https://github.com/apache/maven-resolver/blob/maven-resolver-1.9.14/maven-resolver-impl/src/main/java/org/eclipse/aether/internal/impl/DefaultTransporterProvider.java#L58

(injects Set, only to pass to method using Collection and primate member is Collection as well).
